CULTIYATOR.

SPEGIFIGAT IbN forming part of Letters Patent No. 276,94, dated May 1, 1883..

To all whom away concern.- r r 1 Beitknovvnthat L'Moams L. UTTER, aciti- Zen of the United States,-residingin the city of Rockford, in the county of Winnebago and State of Illinois, have invented a new and usefuhlmprovement in (Jultivators,'of which the 1 following isa specification:

This invention relates to that class of cultivatorsknown as ridingstraddle-row cultiva- IO tors, p. a e x The object ofthis invention is to provide means by which the freeor shovel-supporting endiof thesho'vel-beamsmay be supported in I aproperrelativepositionsubstantiallyparallel r [5 r r r n when ii -use, in cultivating billed or rowed Iwiththe lineot' movement of the machine,

crops on a hill-side without extra exertion on the partof lhe operator. To this .endI have designed, constructed, and applied the device represented in the accdmpanyingdrawin gs, in

At G are represented convergingbeams fixed to axle-tree B, and forward thereof connect with the tongue D. e t At E is represented a transverse beam fixed to the under side of the converging beams and tongue in. advance of the axle-tree.

The depending end portions of thesWay-bar ha f, connec- All the above parts ineveiyp iculafi are substantially the same, joined "in the same inanthe cultivator patented to the November 27, 18 77, and numbered 197,503 i At a. are represented bracketsg i this instance of bar material round in seetionn fitted to engage the axle-tree andfthekconverging.

Application filed July 27, 1882. (N model.)

At 1) isreprese nted a spiralspring having a free ring or thimble connection'with the horizontal portion of the bracket fixed to the main frame in such a manner that the spring will be free to slide lengthwise on the bracket.

At 0 is represented an an gle-formed bracketplate fitted to engage the central or crown portion of the sway-bars,to which it is removably fixed in an adjustable manner by means of a set or clamping screw-bolt. The horizontal portion of this bracket is provided with a series of holes, 01, provided on one side with a radial slot. The free end ofthe spiral spring is provided with a hook-formed stud provided with a lip or blade projecting from the side of its end portion in key-like form. This bookfornned stud, with its key-like blade is adapted to enter the radially-slotted holes (1 in the bracket-plate. The relative position of the radial slot in the holes in the bracketplate' and the key-like blade of the hook-stud are such that when the stud is inserted in the plate the key-like blade will turn away from the radial slot, and will prevent the accidental disengagement of the stud from the plate, but

in such a manner as to be readily disengaged or l e-engaged.

In acultivator having my improvement at tached, when in use on a hill-side, the spring on the side of the cultivator onthe upper side of the hill is connected with the bracket-plate andadjusted in its connection therewith as near as may be within the provisions of the device to exert a sufficient force to hold the shovel-beams in a position substantially parallel with the direction of its forward move ments, and in such a manner as to enable the operator without extra exertion to. carry the shovel-beams to either side for the purpose of properly cultivating the plants, substantially in the same manner as in the use of the culti l vator on level land without the employmentof my improvement. These springs are arranged on both sides of the machine in'such a manner that either can be usedto adapt the ma chine for use in a back-and-forth movement on the same hill-side or in the same direction on opposite hill-sides. In this instance I have employed a spiral spring in one piece, having a slipping or sliding connection on their bracket-supports on the main frame to permit of alateral movement of the shoveLbeams beyond the capacity of the springs; but this same result can be obtained without the slipping action of the spring by the employment of a centrally-l-ink-jeinted two-part spring,in which instance its outer end may have a suitablyfixed link or hinge connection with the main frame.

From the foregoing it will be seen that I produce a spring-connection between the main frame and'the shovel-beams of the cultivator, by which I render it an efficient machine for the cultivation of crops on the hill-side.

I claim as my invention- 1. The combination, with the supporting frame ot' a cultivator, and with the-sway-bar having a suitable connection with the shovelbeams, of a spring connected to the main frame and adapted to be connected with the sway-bar, for the purpose and substantially as described.

2. The combination, with the supportingframe of a cultivator, and with the sway-bar having a suitable connection with the shovelbeams, of springs connected to the main frame upon opposite sides thereof, either of which is 'adapted'to be connected with the sway-bar,

3. The combination, with the supportingframe of a cultivator, and with p the sway-bar having a suitable connection with the shovelbeams, of a spring connected to the sway-bar and to the supporting-frame, and capable ofa sliding movement on its bracket-connection with said supporting-frame, substantially as and for the purpose set forth.

4:- The combination, withthe supportingframe of a cultivator, and with the sway-bar having a connection with the-shovel-beams, of a spring having a bracket-connection with the main frame and an adjustable detachable connection with the swaybar, substantially as and for the purpose set forth.

5. The combination, with the sway-bar connected with the shovelbeams, of an angle bracket-plate detachably connected with the sway-bar, and a' spring connected with the supportingframe, and having an adjustable detachable locking-connection with the angle bracket -plate, substantially as and' ,for the purpose set forth.
